An: OWFS (One-wire file system) discussion and help
Betreff: [Owfs-developers] 1-wire door position sensing
I've done a fair amount of googling tonight which uncovered several
mentions of using 1-wire for door position sensing, but no solid
references to a specific circuit design for doing so (I'm capable of
soldering from a schematic, but an EE I'm not). Looking to extend
1-wire coverage for simple monitoring to ensure the garage door has
been closed. Does anyone have a pointer to a circuit design for such a
thing?
FYI, I received the following offer via email recently, passing along
in case others can use it for their parts orders.
